What test 3 means???

Abhishek Sahoo on 16 Apr 2017

The question is simple yet really well thought. One of my very fundamental concepts got clarified after solving this problem.

Please, edit the problem to make it clear 'eval' cannot be used.

Rafael Hernandez-Walls on 21 Aug 2017

I think same like Fulaninho de Tal, You need edit the problem and it clear 'eval' and 'str2func' cannot be used.

How do do want to handle when the index is bigger than the size of the array? In solution 2 or 3 you enter a 5x5 array, but request slice index 10.
